Fire a water gun

Object Project
As I was a child, I was obsessed with guns, big fan of counter strike 1.6
In real life I had dozens of BB guns, not only I collected them I also took them apart and combined to upgrade the gun, that's my personal attachment to the object chosen for this project.
Object Project consists throughout observation, and exploration and investigation upon a single object, through the making of orthographic drawings, fin model, exploded view drawing and sequential drawing (operating instruction/ user manual).
Water gun: Super Soaker Xtra Power 270 made by LARAMI in 1999
